Hi, I am trying to get my text to be a random colour of either blue, yellow or red. It is for a *very* simple stroop test on psychtoolbox in matlab.
DrawformattedText(w, thisStimulus, 'center', 'center', [], 60)
I am wondering if there is a way to insert a function which randomly sets the text to one of those three colours? That could be either inserted in the DrawformattedText brackets or at the beginning of the trial.
Thanks in advance

DrawformattedText is part of psychtoolbox but not part of MATLAB.
cmap = [0 0 1; %blue
1 1 0; %yellow
1 0 0]; %red
color = cmap(randi(size(cmap,1)),:);
DrawformattedText(w, thisStimulus, 'center', 'center', color, 60)
